Causes and symptoms of white spots on the skin

held versicolor

Tinea versicolor can appear as white patches or spots in shades of pink, red and brown. They are more noticeable on dark skin and can increase over time . These spots can appear with symptoms such as itching, scaly skin and dryness. Everyone has microscopic yeast on their skin, but people with tinea versicolor experience an overgrowth of the yeast.

  • It is not clear why this happens, but it can be caused by:
  • Excessive sweating
  • Oil skin
  • hot and humid environment
  • E weakened immune system

Tinea versicolor occurs most often in people who live in tropical climates. It can affect people of any ethnic group . Justin they may be more susceptible than people in other age groups because of their oily skin.


Eczema ( atopic dermatitis ) is characterized by itchy red rashes with raised bumps. These rashes can appear with white spots . Affected areas are typically the face, scalp, hands, feet, elbows, eyelids, wrists and back of the knees. Rashes are itchy, so scratching can cause sores. Over time, the areas of the body most affected by eczema can become thick, dry and scaly. Eczema rashes can flare up and go away without an obvious pattern. The symptoms can even remain for years.

eczema it is common in children, but can affect people of any age . It can be a lifelong condition. It usually starts before age 5, but it can start before age. It is also common in people who have allergies, such as hay fever.


Vitiligo occurs when certain skin cells called melanocytes stop producing melanin . Melanin is the pigment that gives color to the skin, hair and eyes. Without pigment, white spots form. These spots can appear anywhere on the body. Vitiligo is usually symmetrical, although it only appears on one side of the body. Typically affected areas are the knees, hands, genitals, and hair. It can also affect areas with mucous membranes, such as the inside of the mouth and nose.

Vitiligo usually develops around age 20, but can occur at any age. Its cause is unknown today . This condition can be related to genetics or autoimmune diseases, such as hyperthyroidism.

Idiopathic guttate hypomelanosis

Idiopathic guttate hypomelanosis manifests itself as small white spots on the skin that receives large amounts of sunlight . It appears especially in the arms and legs. These spots are painless and benign. This condition is more common in people with fair skin and can occur in women at a younger age than in men. However, it usually affects women over the age of 40 more.

Pityriasis alba

Pityriasis alba usually begins as pink, slightly scaly patches on the chin and cheeks. They can be round, oval or irregular in shape and are usually dry and scaly to the touch.   These plates can go away on their own or turn white over time .

The skin disease is mostly found in children and adolescents. So it is more likely to occur in people with dark skin . Pityriasis alba is probably related to eczema.

Lichen sclerosus

Lichen sclerosus is a rare condition seen in young and old people . In women, it causes white patches of thin skin, usually around the anus and vulva. In men, the disorder tends to affect the foreskin of the penis. It can also be found in other areas of the body.

Mild cases may not show any other noticeable symptoms. Nevertheless, if symptoms occur, they may include the following :

  • Painful intercourse
  • severe itching
  • Difficulty urinating
  • Skin, the simple bruises or tears
  • Bleeding
  • burn

lichen sclerosus has no known cause , although hormonal imbalance or an overactive immune system may play a role.
